TO ALL WHOM IT MAY OONCERN:

Be it known that we, THEODORE Schuurman and I-Inijnr MonnrsoN, both of the city of Paterson, in the county of Passaic, -in the State of New Jersey, have invented a new and-useful Improvement in Traction- Engines, and we do hereby declarey that the-following isa full and clear description of the construction and operation of the same, reference being had to the accompanying drawings, and-to tlieletters of reference marked thereon. l

Similar letters represent similar parts in all the figures.

The nature of this invention consists in the arrangement of double clutches attached to the driving-shaft, in connection with levers acted on by a steampiston,and operating as springs to keep the clutches in gear, said clutches being connected through suitable chains with Ithe driving-wheels, hung upon independent axles on each side of the boiler. Further, in the arrangement and combination of the driving-engine and truck foi-thc forward wheels, turning together on a suitable 'frameor pin, and through which the steam and exhaust-pipes of the cylinder pass. And further, in l'the arrangement of hydraulic pressure, to operate'the chains of the steeringwheel or drum, Afor the purpose of turning thereby the forward truck with its wheels and motive-power.

In the accompanying drawings, A represents the steam-boiler, B the reboX,'and`O the smoke-box. D D are the steam-cylinders, arranged on each side of the smoke-box, and acting' on the cranks-E, fast on the ends of the driving-shaft F. On each side ofthe shaft F, (inal line with the wheels G, fast to the driving-wheels IL) the loose part of the clutch J is iiXed, turning freely on, said shaft between suitable collars. This-loose part J of the clutch is arranged with two sets of teeth, acting in opposite directions. On the shaft F a clutch, K, is xcd, working o'r sliding upon a feather, fast to said shaft F, and Aprovided with teeth corresponding witlrthe inner set of teeth o'n the loose clutch J. Upon this clutch K, another clutch, L, is xed, sliding upon a feather or key, fast to the outer circumference of this inner clutch K, and provided with teeth corresponding with the outer-set of teeth on thevloose clutch J. 'Io the outer circumference of the clutch, Ina lever of the first order,

a, is arranged, and to the circumference of a projecting part of the clutch K a lever, b, of the third order is applied. The opposite end of 'the lever a is connected through a link, c, with the lever b. Between these two sets of clutches and their respective levers a steam-cylinder, M, is arranged, provided with two pistons, one of which is connected to the lever b, operating the clutches o'n one end of the driving-shaft, and the other piston is connected with the lever; operating the clutches onv the opposite end of the drivingshaft. vThe cylinder M'is provided with steam-pipes, to introduce the steam'either into'both ends of the cylinder, on opposite sides of the pistons, or to introduce the steam between the pistons, so as to force the'same apart towards. each end, said pistons operating thereby the levers in such a manner as to move-the clutches L against the clutches J,Yand their teeth in connection with the corresponding teeth on the clutches J, and at the same time move the clutches K away from the clutches J', or vice versa, as may be desired. The steam acting against these pistons in either position acts at the same time as a cushion or spring, andallows any4 extreme strain or great obstruction upon either of the driving-wheels tocause itsclutch J to disengage itself from its corresponding fast clutch until this strainer obstruction. is removed, when the two parts of the clutch will move into gear again without. having disturbed thereby the other 'clutchl On each side of the re-box Btwo frames, N N, are arranged, between which the 'driving-wheels H are placed, their axles being supported in suitable bearings in said frames. By this arrangement of placing the wheels on separate and independent axles, we obtain not only the advantage' of one wheelbeing capable of running faster or slower than the other wheel, but the position of said wheels may likewise he better adapted to the general arrangement of the engine' and' the more equal distribution'ot` the weight; besideswhich, theaxle of each wheel being supported on each side of the wheel, thejou'rnals of the' same can be made considerably smaller, reducing thereby the friction; Y

On the-sides ofthese driving-wheels H, suitable wheels, G, are attached, which are connected, through straps, bands, or chains, O, with their loose clutches J', communicating thereby, when -these clutches J are in gear, either with the clutch K or with the clutch L,l theA desired motion to the driving-wheels H.

The forward' wheels P P are arranged on a suitable truck, Q, to the underside ot which the steam-cylinder U, with its necessary gearing, is atixed, acting on a shaft, d, fromY which the motion is communicated to the wheels P bymcans-of straps or chains. OnA Athis truck a plate,f, is alixed, provided with n. centre-pin, R,

containing suitable'passageways for'the steam end exhaust.

This centre-pin R Afits in a socket, S, having at its lower cada plate, t, attached, resting on -the platef, fast to the top of the truck Q. The upper part of thissocket S is made square, and lits against and between the sides of the guide-piece T, attached to the under sideof the smoke-box C, said guide-piece T, and consequently the smoke-box C, or end of the boiler, being thereby supported on this socket-S. The guides T steady the socket S crossways/while the lower or round part, into which the centre-pin R lits, and which is firmly attached to the' truck Q, can turn around this centre in `either direction. To the 'exhaust-passage' inthe centre-pin R a pipe, g, is attached, to lead the exhaust into the smoke-box C or i'nto the chimney, in the usual manner, and toA the steam-passage in said centre-pin R a pipe, 7c, is attached, to conduct the steam from thesteamboiler A to this steam-passage. Fromthe lower end ot' these exhaust andstearn-passages, in the centre-pin R, steam and exhaust-pipes are arranged, leadingto the cylinder U or its valve-chamber. By thisattachment of the cylinder, which operates the wheels P, to the truck Q, in the manner described, said whe'elsP can always be oper-ated in whatever position the wheels or truck may be placed or moved for the purpose ot'steering thc engine. I Instead of communicating the niotion of the cylinder VU to an intermediate shaft, d, from which-the same is transmitted through chains or gearing to the wheels P, as here represented, this cylinder or cylinders may be arranged to uct upon the said wheels directly, if it should he desired. Y

To the platef a cylinder or drum, V, is firmly attached, around whichl thev steering-ropes or chains 'w (ses Fig. Il, sheet I) are attached. To the main -i'ranle of the engine two cylinders, W, `are aixed, provided with suitable pistons, t', and piston-rods, u, which latter pass through suitable packed boxes in the heads of said cylinders. The ends of these piston-rods u are attached to the ends of the steering-crds or chains w. To the ends of these cylinders W, near the heads offthe same, pipes, m m, are attached, connected with a. steam cr forcepump, X, and 'arranged in such a. manner that through s ,uaid pipes the cylinders W may either be lled with water or other lluids,or that the liquid may be drawn out of either cylinder and forced into the other cylinder, as may be desired.

The ropes or chains w being attached to the ends of the piston-rods n, water or' other duid is forced into these cylinders W, forcing the Vpistons z' outwards until the ropes or chains fw, wound around and attachedl t0 the wheel-or drum V,are stretched perfectly tight. When the truck Q, with the wheels P, `requires to be moved in either the one or the otherdirection, the water or -uid is then pumped out of one cylinder'and forced into the other cylinder, whereby the chain around one side of the vdrum V is relieved-and the chain around the other side pulled upon, and by which operation the said drum, and consequently the truck Q, with itswheels P, and all other parts attached to the truck Q', are turned around the centre-pin R. By this arrangement these steering` ropes or chains are, through the pressure of the water or fluid in the cylinders 'W against the pistons t, kept perfectly tight in whatever position the truck may be placed, while at the same time a certain elasticity will be obtained in case'either the one or the other ofthe wheels should meet withl any sudden obstruction.

What we claim as our invention, and desire to secure by Letters Patent, is l 1. We claim, in traction-engines lfor common roads, supporting each wheel on an independent short axle,

running in suitable bearings, situated on each side, and close to the wheel, in the manner and for the purpose 4 l described.

2. W'e further claim the arrangement ofthe loose clutch J, and the internal and external clutches K and L, in combination with the levers a and b, or their equivalent, operated by the steam-cylinder M, the whole being arranged and combined in the manner and for the purpose substantially as set forth.

3. We further claim connecting the driving-wheels H with the drivingshaft F through chains, or their equivalents, passing overclutches, arranged and operating substantially as specied. V

4. Te further claim driving. the forward wheels P P by a separate andv independent cylinder orcylind'ers attached to the movable truck Q, and turning with said truck and wheels.

5. We also claim the centre-pin R, fast to the'truck Q, with suitable passages for the steam and exhaust through said centre-pin, in combination with the socket S and guide-frame T, supporting the smoke-box C, or end of the boilerhthe whole being constructed and arranged in the manner and for the purpose described.

6. We further claim operating the ropes or chains that turn the forward truck and wheels of the engine, to guide or direct its movements by means oi' hydraulic cylinders operated by a force or steam-pump, substantially in the manner and for the purpose set forth and described.
